Answer:

2.25 inches

Step-by-step explanation:

The mean, or the average, or the rainfall amounts, can be found by adding all of the amounts together and dividing by the number of amounts. In this case, $\frac{3+2+1+3}{4}=\frac{9}{4}=2.25$ . Hope this helps!

Solve by using the square root method (x-3)2 +4=125

AveGali [126]

Answer:

x= 127/2

Step-by-step explanation:

Let's solve your equation step-by-step.

(x−3)(2)+4=125

Step 1: Simplify both sides of the equation.

(x−3)(2)+4=125

(x)(2)+(−3)(2)+4=125(Distribute)

2x+−6+4=125

(2x)+(−6+4)=125(Combine Like Terms)

2x+−2=125

2x−2=125

Step 2: Add 2 to both sides.

2x−2+2=125+2

2x=127

Step 3: Divide both sides by 2.

2x/2 = 127/2

x=127/2

Lyles height is twice the difference of the height of his brother, harry, and the height of his dad, vince. Lyle is 2 1/2 feet t

Greeley [361]

Answer:

$5 = 19 - 4v$

Step-by-step explanation:

We are given the following in the question:

$\text{Lyle's height} = 2( \text{Harry's height - Vince's height})$

Let l be Lyle's height, h be Harry's height and v be Vince's height.

Thus, we can write:

$l = 2(h-v)$

Lyle's Height =

$2\dfrac{1}{2}\text{ feet}$

Harry's height =

$4\dfrac{3}{4}\text{ feet}$

Putting the value in the equation:

$2\dfrac{1}{2} = 2(4\dfrac{3}{4}- v)\\\\\dfrac{5}{2} = \dfrac{19}{2} - 2v\\\\5 = 19 - 4v\\4v = 19-5\\\\v = \dfrac{14}{4}\\\\v = 3\dfrac{2}{4} = 3\dfrac{1}{2}$

Thus, Vince's height is 3.5 feet.
